<p>These properties specify language standard versions which are requested. When a
newer standard is specified than is supported by the compiler, then it will
fallback to the latest supported standard. This &quot;decay&quot; behavior may be
controlled with the <span class="target" id="index-0-prop_tgt:&lt;LANG&gt;_STANDARD_REQUIRED"></span><a class="reference internal" href="LANG_STANDARD_REQUIRED.html#prop_tgt:&lt;LANG&gt;_STANDARD_REQUIRED" title="&lt;LANG&gt;_STANDARD_REQUIRED"><code class="xref cmake cmake-prop_tgt docutils literal notranslate"><span class="pre">&lt;LANG&gt;_STANDARD_REQUIRED</span></code></a> target property.</p>
<p>Note that the actual language standard used may be higher than that specified
by <code class="docutils literal notranslate"><span class="pre">&lt;LANG&gt;_STANDARD</span></code>, regardless of the value of
